Time to keep an eye on dams again in South Carolina.

State regulators requested dam owners to start inspections Friday with more heavy rainfall expected between Sunday and Tuesday.

Dam owners also are asked to lower water levels, if needed, and clean spillways of trash and debris, the S.C. Department of Health and Environmental Control said.

Owners are asked to monitor their dams during the storm and issue warnings to residents downstream and call local law enforcement if a breach is possible.

At least 36 dams failed statewide — almost half in Richland County — after more than a foot of rain fell on the weekend of Oct. 3-4.

Many more earthen dams were damaged in the historic storm.

DHEC ordered water levels lowered at 75 ponds and lakes two weeks ago to prevent more damage.

Forecasts call for up to four inches of rain in some parts of the Midlands and Upstate between Sunday and Tuesday.

"Dam owners should be aware of the conditions at their dams during such events," said Chuck Gorman with DHEC's dam safety program.
